(ci. .2o-4s) 2 Claims.

A further object of my invention is to provide I an assembly of the foregoing described character wherein certain of the parts may be adjusted to provide desired ventilation.

An important object of my invention is to provide a device of the character described which is simple in construction, durable in use, emcient in operation and economical in manufacture.

With the above and other objects in view, as will hereinafter appear, the invention consists in the combination, and arrangement of parts hereinafter set forth and illustrated in the accompanying drawings, from which the several features of the invention and the advantages attained thereby will be readily understood by those in the art.

Referring to the drawings wherein like reference characters designate like parts throughout the several views:

Each stile I1 In practising my invenucn.,a.s 'illustrated in the drawings, I provide a window frame assembly 9, comprising a frame III equipped with a pair of top and bottom sliding sashes II and I2 respectively; The frame III. is provided with inner and outer casings I3 and I 4 respectively connected together at their upper ends by a head plate I5 and at their lower ends by alsubsill I8. 'I'he sides of the casing I3 and I4 are connected together by means of a pair of stiles I I which oppose the side end faces I8 of the sashes. The outer casing I4, adjacent the stiles I5, is formed with an inwardly disposed bead I9 serving as an outer guide for the top sash II while the head plate I5 is provided on its lower face with a longitudinally disposed strip 20 for engaging the inner face of the upper rail 2I of said upper sash as clearly illustrated in Figure 1 of the drawings.

The-inner end of the subsilly I6 has secured thereto a sill 22, the latter being provided with an outwardly disposed face 23 for engaging the inner facev of the lower rail 24 of the bottom sash. lWhen the bottom sash is in closed condition, the outer faces of its side rails 25 are disposed in sliding engagement with parting strips the stiles I'l, said parting strips 26 26v carried by having their upper ends terminating interjacent the upper and lower faces of the meeting rails 21 and 28 of the top and bottom sashes respectively when the latter are in closed positions. is fashioned with a pair of spaced a grooves'29 and 30 respectively and with the upper Figure 1 is a vertical sectional view of a window assembly constructed in accordance with my invention.

Figure 2 is a view similar to Figure 1 but illustrating the sashes in reverse positions.

Figure 3 is a sectional view taken on the line 3 3 of Figure 1.

Figure 4 is a detail enlarged vertical sectional view of the upper portion of the window frame.

Figure 5 is a view similar to Figure 1 but illustrating the top sash inpartially reversed position.

Figure 6 is a vertical sectional view of the upper portion of 'the assembly and illustrating the bottom sash in partially reversed position.

Figure 7 is a detail sectional view of the bottom sash and illustrating the means of connecting the end of a sash cord to .the lower trunnion.

Figure 8 isa perspective view of the inner stop. Figure 9 is a perspective view of the outer stop.

ends of said grooves communicating with a transverse slot 3| extending between the groove 28 and the inner casing I3 as clearly illustrated in Figure 4. 'I'he upper end of the groove 29 extends an appreciable distance superjacent the slot 3| and receives therein a trunnion 32 extending later'- ally from the end face the upper end of the latter.

'Ihe trunnions 32 are adapted to be vertically operated within the grooves 29 during vertical shifting of the top .sash and to be laterally shifted into the slots 3| whereby to permit the upper end of the top sash to be actuated out of the conflnes of the frame forpositioning in a manner to dispose its upper rail 2l in lapped relation with the lower rail 24 of the lower sash when the latter is reversed as hereinafter set l forth The head plate I5 has mounted thereon, superjacent the top sash, agpair of pulleys 33 over which are trained sash cords 34 having coincident or outer ends connected to sash weights I1 and plate I8 of the top sash II at y -of the topsash as The inner ends of the sash cords 34 are pivotally connected, within said recesses 35, to the side rails 36 of the top sash superjacent the meeting rail 2l as at 31.

Each side face I8 of the bottom sash is provided with a pair of upper and lower trunnions 38 and 39 extending outwardly from the lower and meeting rails 24 and 28 respectively for vertical operation within the adjacent groove 3|! of the respective stile I1. Subjacent the slots 3|, the stiles are formed with recesses intersected by the grooves 38 and in which are disposed a pair ofpulleys 40 having trained thereover sash cords 4I. Coincident or outer ends of said sash cords 4I are attached to sash weights (not shown) while the other or inner ends extend downwardly through the grooves 30 andare pivotally connected to the trunnions 39 therein, it being w1- derstood that the trunnions 39 are of a greater length than the trimnions 381 whereby to permit the latter to be disposed and operated in confronting relation with the sash cords 4I. When the lower sash is operated to raised position', the trunnions 38 are actuated laterally through slots 3|, between the grooves 38 and the inner casing I3, to permit the top of the bottom sash to be pivoted about its lower rail and with the trunnions 39 serving as pivots during the pivoting movement. When the bottom sash is thus operated, the meeting rail 28 is disposed in engagement with the sill 22 and the `bottom rail 24 in lapped relation with the upper rail 2| of the top sash when the latter has been reversibly operated as heretofore described and as illustrated in Figure 2.

In order to preclude lateral displacement of the sashes, each stile is equipped with a pair of outer and inner stops 42 and 43 acacent the upper ends of the grooves 29 and 38 respectively, said stops being pivotally mounted within recesses formed in the'stile superjacent the slot 3| to permit the slots to be operated laterally through the frame. The stop 42 is provided with an arm 44 adapted to overly the slot 3|, postjacent the groove 23 for seating within a recess 45 formed in the stile. The arm 44 thus engages the adjacent trunnion 32 of the upper sash and, while permitting vertical adjustment of the top sash, precludes lateral displacement thereof. When the arm 44 is disposed in raised position above the slot 3|, the adjacent trunnion 32 may be operated through said slot 3| to effect reversing heretofore described.

Each stop 43 is formed with a pair of arms 46 adapted to overly the slot 3| on each side of the groove 30 for seating engagement within a pair of recesses 41 formed in the respective stile. 'I'he arms 46 serve to engage the adjacent trunnion seals between the sashes and the bead and parting strips.

Each stile I1 is formed, interlacent its ends, with transverse channel 50 disposed slightly above the meeting rail 28 -of the bottom sash when the latter is in closed position.- `'I'he outer ends of said channels y50 communicate with the grooves while their inner ends terminate, prejacent the inner casing I3 and are formed with subjacent seats 5| for receiving therein the trunnions 38 whereby said lower sash is maintained in a slightly raised position with respect to the sill 22 to afford ventilation.

From the foregoing it will be apparent that I have provided a window assembly wherein the sliding sashes are so' connected and arranged with respect t the frame that they may be actuated to reverse position to permit the panes to .be readily cleaned from the interior of a building. It will also be apparent that the sashes are operated to reverse positions in a manner to preclude engagement with a screen 52 or the like mounted within the outer casing I4 of the frame.

Without further elaboration the foregoing will l so fully explain the invention that others may,

Vby applying current knowledge, .readily adapt the same for use under various conditions of service. Moreover, it is not indispensable that all the features of the invention be used conjointly since they may be employed advantageously in various combinations and sub-combinations.

It is obvious that the invention is not conned tothe herein described use therefor as it may be utilized for any purpose to which it is adaptable. It is therefore to be understood that the `invention is not limited to the specific construction as illustrated and described as the same is only illustrative of the principles of operation, which are capable of extended application in various forms, and that the invention comprehends all construction within the scope of the appended claims.
